Few studies explored trajectories of depressive symptoms from early pregnancy and covered the whole perinatal period. This study aimed to explore the trajectories of perinatal depressive symptoms, their heterogeneity of onsets and peaks, and relations to demographic and psychological factors.
A longitudinal study was conducted at two hospitals in China amongst 1,126 participants. Perinatal depression was measured using the Edinburgh Postnatal Depression Scale. Demographic and psychological factors were collected by self-developed questionnaire and Generalized Anxiety Disorder-7. Women completing at least three depression screens (n=879) were included. Latent Growth Curve Model and Growth Mixture Model were performed to identify the depression trajectories and logistic regression was used to analyse factors of trajectories.
Three trajectories were identified 90.0% of women never presented with depressive symptoms ("Low-throughout"); 5.1% presented with depressive symptoms mainly during the antenatal perid with each trajectory were different, raising the potential of individualized intervention to reduce the occurrence of depression.Despite recent growth, opportunities for preclinical medical students to engage with the field of wilderness medicine remain geographically, financially, and logistically limited. Attendees of the 2018 Mid-Atlantic Student Wilderness Medicine Conference were invited to complete a post hoc web-based survey after the event. Results of the survey were analyzed to determine the demographic characteristics and motivating factors for attendance, as well as perceived conference performance and future behavioral intention of survey respondents. https://www.selleckchem.com/products/wnt-agonist-1.html The majority of attendees were preclinical level medical students, 37% of whom were affiliated with their institutions' wilderness medicine interest group and 40% of whom were affiliated with an emergency medicine interest group. Intrinsically motivating factors such as personal interest and opportunities for educational enrichment were significantly more important in determining conference attendance than extrinsically motivating factors such as cost and networking opportunities. Data from this conference support many encouraging trends and suggest that regional conferences may represent a practical way to increase access to wilderness medicine in the preclinical medical student population and thereby influence career decision.The UK undergraduate medicine curriculum provides insufficient opportunities for medical students to explore the field of wilderness medicine, despite interest in the area. The student-led Cambridge University Wilderness Medicine Society devised a low-cost wilderness medicine teaching weekend that can be replicated at other institutions.
The weekend course consisted of small-group lessons introducing the roles of the expedition doctor and expedition leader and the assessment and management of acute conditions in remote environments. This was followed by a 3-station circuit to teach the principles of casualty triage, splinting, and construction of rope stretchers. These skills were then practiced in simulations in which participants rotated roles as care providers and patients. Participant confidence was compared before the course and immediately on course completion using the related-samples Wilcoxon signed-ranks test with significance accepted at P&lt;0.05. Usefulness of course content and perceptions ofate curriculum.We developed an elective course titled Medicine in Extreme Environments (MEE) at the University of Texas Southwestern Medical Center for first- and second-year medical students. This course covered physiology, research, clinical practice, and career guidance regarding the fields of wilderness, space, hyperbaric, combat, and exercise medicine. The primary aim was to generate interest in and awareness of these seldom covered fields of medicine by exposing medical students to these disciplines during their preclinical years. A postcourse questionnaire was implemented to investigate whether the MEE course increased awareness of, interest in, and knowledge in the fields of medicine included in the curriculum. Through 2 iterations of the class, a total of 67 students enrolled in the course, and 38 students completed the questionnaire. After course completion, 95% felt they better understood the work and lifestyle of the fields covered, 100% learned more about concepts of each field, and 74% agreed that the elective influenced the direction of their future careers to include some part of the fields emphasized. Although only a limited number of students enrolled in this course, these initial findings suggest that the MEE curriculum may have some utility in promoting awareness of and interest in these medical disciplines among students who attend the course. With continued student and faculty support, this course will likely be continued annually at our institution. We believe that certain aspects of this course may be useful in helping develop similar courses at other medical schools.Arsenic (As) is a worldwide human health issue with the major exposure route being the consumption of As-contaminated drinking water. Sorption is considered to be an efficient treatment method, among other technologies, for As removal from various water and wastewater matrices. There are common commercially available sorbents, however, the use of locally or regionally available biomasses have recently been of interest as potentially cost-effective and environmentally friendly alternatives. Despite these benefits, untreated biomasses often show low sorption capacity, can be too fragile, and can lead to coloration of waters when used in treatment processes. Treatment methods of biomasses can include chemical processes using acid or alkaline solutions, developing of biomass composite by deposition of activating agents, and preparation of biochars. This review includes an overview of 53 recent studies that assess a variety of biomass modification methods meant to overcome these issues such as activation with acids or bases and biomass-based composites. Furthermore, future perspectives have been provided to assist in the further optimization of methods for biomass modifications to enhance their As sorption capacities.
